在Ubuntu 18.04上反应本机Android模拟器错误 [英] React native Android emulator error on Ubuntu 18.04

问题描述

我正在尝试设置本机反应以在android模拟器上工作.我正在使用Ubuntu 18.04.我尝试使用"react-native run-android"时收到此错误消息:

I am trying to setup react native to work on an android emulator. I am using Ubuntu 18.04. I am getting this error message when i try to use "react-native run-android":

BUILD FAILED in 1m 21s

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

Command failed: ./gradlew installDebug

此外，它说:

A problem was found with the configuration of task ‘:app:installDebug’. File ‘/home/william/Android/platform-tools/adb’ specified for property ‘adbExe’ does not exist.

在我的本机项目中，我找到了一个答案，说在我的settings.gradle中将"/"替换为".但是，其中唯一的文件是:rootProject.name =‘AwesomeProject’包括‘:app’

I found an answer that said to replace ‘/’ with ‘’ in my settings.gradle in my react native project. The only thing in that is file however is: rootProject.name = ‘AwesomeProject’ include ‘:app’

我添加了:

export PATH="$HOME/bin:$PATH"
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

直到我的bashrc的结尾.

To the end of my bashrc.

推荐答案

对我来说，解决方案是创建android/local.properties文件并在磁盘上指定SDK路径 sdk.dir=/username/Android/Sdk

solution for me was to create android/local.properties file and specify SDK path on your disk sdk.dir=/username/Android/Sdk
